          WHEREAS, the Company has obtained the written consent of the Holders
of at least a majority of the outstanding Notes as of March 8, 1996, to amend
Section 5.06(b)(H) of the Indenture, with such amendment to be effectuated by a

Indenture to the Indenture.

          WHEREAS, upon the request of the Company and the Guarantor,
accompanied by resolutions of the Boards of Directors of the Company and the
Guarantor authorizing the execution of the Fourth Supplemental Indenture, and
upon the filing with the Trustee of evidence of the consent of the Holders as

          WHEREAS, the Company and the Guarantor have determined that it is
desirable to enter into this Fourth Supplemental Indenture; and

          WHEREAS, the execution and delivery of this Fourth Supplemental
Indenture have been duly authorized by Resolutions of the Boards of Directors of
the Company and of the Guarantor, and the Company and the Guarantor have
requested the Trustee to join with them in the execution of this Fourth
Supplemental Indenture; and

          WHEREAS, the Trustee has accepted the trusts created by this Fourth
Supplemental Indenture and in evidence thereof has joined in the execution
hereof;

          NOW, THEREFORE, THIS FOURTH SUPPLEMENTAL INDENTURE WITNESSETH, that,
in consideration of the premises and of acceptance by the Trustee of the trusts
created hereby and by the Indenture, and also for and in consideration of the
sum of One Dollar to the Company duly paid by the Trustee at or before the
execution and delivery of this Fourth Supplemental Indenture, the receipt of
which is hereby acknowledged, IT IS HEREBY COVENANTED AND AGREED, by and among
the Company, the Guarantor, and the Trustee, as follows:

          1.  Terms defined in the Indenture are used herein as therein defined.

          2.  Section 5.06(b)(H) of the Indenture is hereby deleted in its
entirety, and the following new Section 5.06(H) of the Indenture shall be
substituted therefor:

              (H)  the Company from (1) making all regular quarterly dividends,
each such quarterly dividend payment not to exceed $487,500 in the aggregate or
$2,437.50 per share, on the outstanding shares of the Company's Series 2D Senior
Preferred Stock; and (2) making all payments of any dividends of up to 9.75% on
the aggregate unpaid amount of any regular quarterly dividend on the outstanding
shares of the Company's Series 2D Senior Preferred Stock from the date such
regular quarterly dividend should have been paid to the date of the payment of
such dividend; in consideration thereof, and except as provided below, the
               ------------------------------------------------------
Company shall increase the Interest payable on the Notes by one percent (1%)
(the "Additional Interest") from March 8, 1996, such Additional Interest payable
as
<PAGE>
 
provided for in the Notes.  The Company files its financial results with the
Securities and Exchange Commission on quarterly and annual reports, and these
reports include the Company's earnings after deducting minority interests and
before interest, taxes, depreciation, and amortization calculated in accordance
with generally accepted accounting principles ("Earnings").  The Company will
measure its Earnings for trailing twelve month periods, each period to end on
the last day of a fiscal quarter and extend no further than March 31, 1998 (each
a "Quarterly Measurement Period").  If  the Company's Earnings equal or exceed
$36 million for two consecutive Quarterly Measurement Periods, then the Company
is relieved of its obligation to pay any future Additional Interest.  However,
if the Company's Earnings do not equal or exceed $36 million for any subsequent
Quarterly Measurement Period, up to and including the Quarterly Measurement
Period ending March 31, 1998, the Company is obligated to commence paying
Additional Interest until the Company's Earnings again equal or exceed $36
million on a trailing twelve month basis calculated quarterly.

Supplemental Indenture:
